This invention is directed to an-improvement in tobacco pipes, wherein provision is made for cooling the smoke from the tobacco, for insuring against any tobacco particles or 5 liquid reaching the mouth of the user, and for preventing any possibility of clogging in The primary object of the invention is the production of a tobacco pipe in which the incoming air is drawn through the stem' remote from the bowl, and compelled ,to travel lengthwise and in opposition to the passage of the smoke in a smoke duct, the incoming air thus servin .to cool the duct and thereby the smoke during the passage of the smoke to the mouth.

A further object is the provision of a receptacle -serving as a condensate chamber,

to which the smoke is initially delivered, this chamber being open to the external influence of the incoming coolair, thus insuring precipitation of any liquid in. the smoke and cooling the smoke through the walls of the chamber.

= A further object (if the invention is the provision of an indirect connection between the stem and bowl to thereby tend to prevent any liquid ortobacco particles from being delivered with the smoke. A further object is to construct and relatively arrange" the various parts of the pipe so that they are readily removable and replaceable when necessary for cleaning or re-.

pair, with the parts conveniently renewable when desired.

The invention'is illustrated in the accompanying drawings, in which-:

Fig. 1 is a longitudinal sectional view of a pipe constructed in accbrdance with the in-.

vention.

Fig. 2 is a section on line 2-2 of Fig; 1. vFig. 3 is a peflxpective view of the tobacco receptacle. t

Fig. 4 is a perspective view of the smoke duct and condensate chamber. 1

The improved pipe includes a bowl 1 and a stem portion 2 integral therewith, such arts aside from the details hereinafter noted being of any shape, size, or material. A mouth piece 3 is arranged for removable conotherwise formed to maintain the desired seal.

nection with the stem 2, the connection being preferably a slip joint, though obviously any type of connection ma. be employed.

A condensate chamber 4 is secured in the bottom of the bowl 1, preferably through the medlum of a screw 5' through the -bot- 3 tom of the bowl and" accessible from the exterior, to permit separation of the chamber when desired. The chamber is preferably of thin metal of high heat conductivity, as, for example, aluminum, and has a diameter somewhat less than the interior diameter of the bowl, as seen in Fig. 1. The bottom of the condensate chamber is of more or less conical form to permit free circulation of air beneath such chamber for cooling purposes. .A smoke duct 6,..preferably of metal of high heat conductivity and of comparatively uninterrupted space surrounding the smoke so duct, for a purpose which will be later explained.

The free, end of the-smoke duct enters a reduced portion of the mouth piece,-indicated at 8, the free end of the .duct being thus sealed against the mouth piece and stem in advance of the free end of the duct. Of" course the duct and mouth piece may be A'tobacco receptacle 9 is designed to be more or less snugly seated within the bowl 1. The receptacle seats at its lower end in the upper open endv of the condensate charnher 4, the upper edge of the-latter being formed to provide a seat for the receptacle,

as indicated in Fig. 1. The receptacle is open at the upper end',.and isformed initsf otherwise closed bottom with a series of open- -ings 10, three'such beingillustrated, whereby free communication is established between i the tobacco receptacle 9 and the condensate chamber 4. The receptacle is fitted tothe bowl,.and the latteris formed on its inner 7 to the top of the receptacle.

The mouth piece, in advance of the sealing junction of the smoke duct therewith, is

'- formed with one or more openings 13, establishing free air inlet to the stem and mouth piece externally of the smoke duct. these openings 13 forming the sole air admissions to the pi p l The bowl, and thereby the tobacco recep tacle is closed by a removable cover 14, fitting the upper edge of the bowl in sealing relation, as indicated in Fig. 1.

The tobacco being laced in, the. tobacco receptacle 9 and lighte suction on the mouth piece in the usual manner causes-air to enter the openings 13-, pass lengthwise the mouth piece and stem, entirely surrounding the smoke duct, pass into the bowl, completelyenveloping the condensate chamber 4, andthrough the channel '11. The air then passes downwardly through the tobacco in the receptacle 9, the smoke and air passing into the condensate receptacle or chamber 4, through the openings 10 in the tobacco receptacle 9 and from the condensate chamber throughthe smoke duct 6.

The smoke duct andcondensate chamber are both open to the influence of the incoming'cool air. As both are Ereferably ofcomparatively thin metal of i h heat conductivity, the cooling efl'ect of t e incoming air is pronounced, and the smoke reaching the -mouth of the user is cool and dry. The coolmg effect on the condensatechamber insures a more or less complete condensation of an contained in the smoke.

y providing a plurality of holes in the:

' tivel large air inlet, little efiort is-required 56 the smoke e rt of'the user in drawing von-the no particles of tobacco can enter duct, the pipe isessentially noncloggmg nor can anygauid enter the mouth. The proyision of the ing cap permits use of the p1pe n high winds, and prevents distribution of lighted particles of tobacco. All parts are readily removable and replaceable,- contributing to the convenience of keep mg the pipe in perfect order and operation. Any part can be removed and replaced by a new part, and particularl the tobacco receptacle, the part subj to greatest wear tending through the stem and being through the .burning tobacco, can be conveniently removed for cleaning or renewal. Of course, the tobacco receptacle which is the only part in contact with the tobacco,

ma be separately made of high grademateria of particular function in connection with burning tobacco, while the remainin arts of the pipe proper that is the stem an wl, may be constructed of inferior material,- thus giving the advantage of a high grade pipe of com aratively little cost.

thus described the invention, what as' new, is v 1. A tobacco pipe including-a bowl, a stem,

-a tobacco receptacle loosely placed in the so bowl, a condensate chamber removably secured in the bowl and in open communication with the tobacco receptacle, a smoke duct leading from the condensate chamber and ex-.

tending len hwise the stem, and means for admitting air through the stem remote from the bowl.

2. A tobacco pipe including a bowl, a stem, a condensate chamber removably secured in the bottom of the bowl, a smoke duct in open communication with said chamber and extending through the'stem, the bottom of the chamber being conical, a tobacco receptacle removably seated on the chamber and formed in its bottom with an opening to establish 05 communication with the chamber, the stem being formed with air inlet openings remote from the .bowland stem juncture.

8. A tobacco pipe having a smoke channel leading through a condensate chamber to the tobacco, said pipe having an air inlet located to compel the entering airto travel-throughout the length of the smoke duct ,and enve o the condensate chamber.

a condensate chamber removably secured in the bottom of the bowl a nd otherwise free of i contact with the bowl, a tobacco receptacler -duct leading from the condensate chamber and through the stem, the stem being formedwith air-inletopenings to admit. air through '5.
